Salut!

Yeah fully aware, just bolted the assembly together for a trial fit.
Didn't want to go to the expense of items before that.
I have identified a neat way to incorporate a support bar but the general consensus is its not needed.
i must admit the assembly feels pretty solid.

There is a support bar shown on the R-Sport catalogue picture. It maybe the same part as the one that supports the E Injection manifold.

That was exactly my idea, use the support bracket from the 1800e!
There was one for ages on fleabay but now gone!
It shouldn't be to hard to fabricate

Russ,
Is the instalation of the Solex carbs now complete?
If so can you comment on what you can tell is the measureable gain over the original SUs?

The idea was to trial fit and ensure the carbs fitted without spending big bucks stripping and rebuilding.
I've been working in Canada a fair bit(currently typing this in a Ottawa hotel) so it's difficult finding time to make a real start. I don't want to start and then find myself stopping and leaving machined components unassembled.
I'm hoping to make a start early April with the carbs being installed once the new engine is in the car. Hopefully some time in May
Then a rolling road session to look at jetting
I will keep the forum posted

just to let you know

your carbs are the early type ADDHE

you have the late type float chamber covers fitted with the early type

jet inspection covers that's why the late type gaskets are sticking out

the late type float chamber covers have the floats hanging form the cover

the early type have the floats in the bowl located on a pin the the carb body

also the outer choke sleves are missing or you can use slide in trumpets

more info here http://www.rmcarburetors.net/addhe_rebuilding%20v2.htm

having said all that you have probably sorted it all out by now seeing as I have just noticed you posted this in 2013!!!

Thanks for the observations
All sorted now, carbs have been on the car for a number of years. I wasn’t aware there was an early or late type jet cover, but as you say it runs fine despite this.
My floats are in the main body.
Volvo supplies these kits with plastic slide in trumpets which are crap. I’ve since changed them but added a purpose fabricated airbox with a feed from the nose cone.
The carbs are proving very reliable, start first time after a couple of pumps and good mileage.
They also perform very well👍

Of course the new jet cover gaskets may have been consolidated to just the one version!

You can still get both types because they are different shapes

I'm looking for a set of 45's and spare parts to replace the Webers on my kit. Who is a good source?
